AC 3 Phase Variable Frequency Drive AFD for CNC Machine
A CNC lathe is a machine tool designed to remove material from a
rotating work piece, using a cutting tool. Some lathes can form
hollow parts by a process called metal spinning. These parts have
circular cross-sections. Metal and other materials can be turned on
a lathe, including wood and plastics. CNC controlled lathes use a
computer to control the process of making each part with repeated
accuracy and precision.
· Precise speed regulation and torque over wide speed range
· Interlock drive with operation of CNC.
· Quick acceleration even under high torque conditions

A variable-frequency drive (VFD) is a system for controlling the
rotational speed of an alternating current (AC) electric motor by
controlling the frequency of the electrical power supplied to the
motor. A variable frequency drive is a specific type of
adjustable-speed drive. Variable-frequency drives are also known as
adjustable-frequency drives (AFD), variable-speed drives (VSD), AC
drives, microdrives or inverter drives. Since the voltage is varied
along with frequency, these are sometimes also called VVVF
(variable voltage variable frequency) drives.
